I saw on another forum, once you take apart the back part of the phone, our phones take a 16gb microsd card. Just curious if anyone tried it and if there's any affect on performance, since *i think* it only takes class 2 32gb cards.
Pretty sure like all HTC phones, the Arrive has a 16GB memory card already, so you are not adding another 16. You are removing 16 and replacing with 32. Some users have tried this on other HTC devices with mixed results. Yes, you do need to factory reset after changing cards. And yes, you do void the warranty. Have fun.
One thing i started doing with my phones is to stop putting all my music on. Make a few playlists and add those.
With WP7 you can make a playlist in the zune software and pick and choose which ones you want synced up and it will do it over wifi.
Once i broke that habit i realized that i realistically only listened to about half my music and between zune pass and last.fm if i really want to hear a songs not on the divice its not too difficult.
